Application filed July 1, 1914. Serial No. 848,458.

[0 all whom it may concern Be it known that I, ALFRED F. MoCoLLUM, a citizen of the United States, residing in Bloomsburg, Columbia county, Pennsylva Pile-lVire, of which the following is a specification.

Hy invention consists of an improved form of pile wire for use in looms for the manufacture of pile fabrics and is particularly serviceable in the weaving of those fabrics in which the wires are inserted transversely to the warp and over which the latter is looped to form the pile of the fabric.

As herein illustrated my invention is especially constructed for use in looms provided with pile cutting mechanism including a pile cutting knife and aseries of grooved wires in which said knife is movable. Heretofore the wires used had rounded convexed bottom portions which rested on the body warp of the fabric and were often tilted or up set, before they were bound in the warp, by the pull of the warp during the change of thesheds, with the result that irregular rows of pile were frequently caused.

One object of my invention therefore, is to so construct the pile Wires that they cannot easily be upset or turned over after they have been inserted in the fabric, it being especially desired to so form the bases of the wires that regardless of whether they I In the above drawings, 1 represents the mam portlon of apile wire having a longitudinally extending groove 2 and secured at one end to a jack-head 3 designed to faciliployed in weaving uncut pile fabrics such as body or tapestry brussels, 0r in the weaving of cut pile fabrics where the pile cutting knives employed are secured to the ends of the pile wires. In any case, under operating conditions, the longitudinal edges 5 and 6 of the base both contact with the ground weave and tend to firmly seat and slightly embed the wire in the fabric with the result that said wire tends to retain its proper position and cannot be easily upset.

1. A pile wire having its fabric-engaging base surface longitudinally recessed.

2. A pile wire having its fabric-engaging base surface recessed to provide a plurality of relatively sharp fabric-engaging edges.

3. A pile wire having its fabric-engaging base surface longitudinally recessed to provide two longitudinally extending relatively sharp fabric-engaging edges.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

ALFRED F. MCGOLLUM.
